Abstract:

In this article,the author discusses the reason why water quality of the Hanjiang River is better than that of the Yangtze River. It is shown that it is because of the differences of geological structures,soil constitution,riverside slopes and river widths,and so on.The author suggests that environmenthydaulic engineering projects should be constructed to regulate rivers,so water in the river will naturally be clear and the limitation of the water purification technology for slightpolluted water process can be conquered.

Key words: the Yangtze River, the Hanjiang River, water quality, environmenthydraulic engineering
